Hash, unlike if, has no order. If the order matters, you might need something like the following (alternatives in regexes match from the leftmost one): `my @keys = ('test', 'dark', 'white', 'house', 'all things', 'money', 'count +ry'); my @values = qw(blue black light home multi value USA); my $regex = join '\|', @keys; # "map quotemeta" might be needed for ugl +ier keys $regex = qr/($regex)/; my %switch; @switch{@keys} = @values; my $change; if ($item =~ $regex) { $change = $switch{$1}; } else { $change = "neutral"; } print "Final Item = $change.\n";` [download] لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l]

Order will not matter, I am more concerned about speed.	[reply]

I liked it! I just fixed this line for future reference: From this: `my $whoopdie = $stuff{param("item")} \|\| "NAOAOAOANOOOO!!!";` [download] To: `my $whoopdie = $stuff{$q->param("item")} \|\| "NAOAOAOANOOOO!!!";` [download] Thanks for the helping!	[reply] [d/l] [select]

It’s fine of course but using CGI.pm as OO has always struck me really silly (UNLESS you’re passing the object to other code). `use CGI ":standard"; param();` La.	[reply] [d/l]
